PHP array reassembly after traversal, please tell me how to do it

As shown in the picture, the code is assembled into the following format. Is there any way? The length of the array is variable

<code>$_POST['huodong']=array(
    'shenbing',
    'duobao',
    'ceshi'
);
$_POST['sttime']=array(
    '2016-11-07 00:00:00',
    '2016-11-08 00:00:00',
    '2016-11-09 00:00:00'
);
$_POST['edtime']=array(
    '2016-11-10 00:00:00',
    '2016-11-11 00:00:00',
    '2016-11-12 00:00:00'
);
$_POST['sourcelmt']=array(
       array(
        'xiaomi_uku_and',
        'uc_uku_and',
        'qq_uku_and'
    ),
    array(
        'xiaomi_uku_and',
        'qq_uku_and'
    ),
    array(
        'uc_uku_and',
    )
);</code>

Now I want to assemble it into this format:

<code>array(
    'shenbing'=>array(
        'sttime'=>'2016-11-07 00:00:00',
        'edtime'=>'2016-11-10 00:00:00',
        sourcelmt=array(
            'xiaomi_uku_and',
            'uc_uku_and',
            'qq_uku_and'
        ),
    ),
    'duobao'=>array(
        'sttime'=>'2016-11-08 00:00:00',
        'edtime'=>'2016-11-11 00:00:00',
        sourcelmt=array(
            'xiaomi_uku_and',
            'qq_uku_and'
        ),
    ),
    'ceshi'=>array(
        'sttime'=>'2016-11-09 00:00:00',
        'edtime'=>'2016-11-12 00:00:00',
        sourcelmt=array(
            uc_uku_and
        ),
    ),
);</code>

Any good ideas? Thanks~

<code>$result = array();
foreach($_POST['huodong'] as $first_key => $id) {
    // 此处的 '' 和 array() 是作为默认值
    foreach(array('sttime'=>'','edtime'=>'','sourcelmt'=>array()) as $second_key => $val) {
        $result[$id][$second_key] = isset($_POST[$second_key][$first_key]) ? $_POST[$second_key][$first_key] : $val;
    }
}
print_r($result);</code>

According to the subscript, just take the value corresponding to the subscript in the array

$result = array();
for($i=0;$i

$result[$_POST['huodong'][$i]]=array(
    'sttime'=>$_POST['sttime'][$i], 
    'edtime'=>$_POST['edtime'][$i],                           
    'sourcelmt'=>$_POST['sourcelmt'][$i],
    );

}
print_r($result);
